ALEXANDER J. ARTHUR, OF FORT DODGE, IOVA.

FOLDING BLIND FOR WINDOWS.

SPECIFICATION forming part of Letters Patent No. 341,542, dated May 11, 1886,

Application filed August 31, 1885. Serial No. 175.682.

To all whom, t may concern:

Be it known that I, ALEXANDER J. ARTHUR, of Fort Dodge, in the county of W'ebster and State of Iowa, have invented an Improvement in Folding Blinds for Vindows, of which the following is a specilication.

In my application No. 159,762, filed March 23, 1885, there are vertical slats connected together edge to edge by hinges, and folding back and forth so as to be closed up against the window-case, and such slats are connected up to form sections adapted to the windowl'rame. Usually foursueh sections will be made use oi'-two in the upper part and two in the lower part of the frame-the places of separation being central, vertical, and horizontal lines.

In my present improvements the slats are hinged together so as to fold in the same manner, and the sections are similarly placed and connected in the windowlrame; but the slats themselves are constructed in the manner hereinafter described, so as to allow for the passage of light and air between the slats.

In the drawings, Figure l is an elevation of several slats placed together and hinged, and Fig. 2 is a section of the slats at the line m m, Fig. l, in larger size.

The slats A A are hinged together at B 13, so as to be folded in opposite directions or zigzag, as in my' aforesaid application, and to close back against the window case or frame. The hinges may be of any desired character, and do not iorm any part of this application. The slats are of suitable Width and thickness, and oi' a length adapted to the Window-frame, so that the section formed of these slats may compose one of the sections used in the Window-frame. Vhere the hinges B are applied,

the edges of the slats are square, or nearly so. Between the hinges, and preferably above and (No model.)

below such hinges, the edges of the slats are beveled, as at O C, so that there are diagonal openings between the slats. These openings admit the passage of the atmosphere for ventilation and allow some light to enter, in order that the blinds may not require to be open during daylight for passage about a room; but too much lightis excluded. Usually the edges of the beveled portions overlap, as shown, the slats at such beveled portions being Wider than they are at the places where the hinges are applied. This prevents the rays of light passing through the joint at right angles to the plane of the blind. The edges of the slats at the inner and outer edges ofthe sections should be square, as at D D, and the slats may be perforated if it is desired to admit more light.

The beveled portions Oilnprove the appearance of the blind. The slats composing the sections extend above and below the hinges. They can be cut or sawed off at either top or bottom, or both, to accommodate smaller sizes of Windows, and one or more slats can be removed if the sections are too wide, or the slats can be lapped and fastened in the middle.

I claim as my invention-- 1. A folding blind having vertical ranges of slats hinged together at alternate edges so as to fold together, and the slats beveled on their edges, except where the hinges are applied, substantially as set forth.

2. The slats for folding Window-blind sec tions, having square edges for the reception of the hinges and beveled edges between the hinges, the slats being wider at the beveled edge than at the square portions, as set forth.

Signed by me this 20th day ot' August, i885.

ALEX. J. ARTHUR.
